SiECIFICATION formingpart of Letters Patent N o. 731 ,07 5, dated June16, 1903. Application filed February 6 ,1902. Serial No. 92 ,932. (Nomodel.)

To all whom it may concern:

Be it known that 1, CHARLES SCOTT-SNELL, a subject of the King of GreatBritain and Ireland, residing at 51 Victoria street, Westminster,London, England, have invented certain new and useful Improvements inAd'- vertising or the Like, (for which I have made application forLetters Patent in Great Britain, No. 15,870, dated August 7, 1901,) ofwhich the following is a specification.

This invention relates to advertising apparatus of the kind whereby anadvertisement is mechanically caused to change in character or tointermittently appear and disappear.

The object of the invention is to provide an apparatus of simpleconstruction by which an advertisement may be gradually exposed and thenafter complete exposure changed orobliterated.

The invention consists in disposing a number of bars adjacent to oneanother in the same plane, the combinedsurfaces orperipheries presentingan advertising-surface, each bar bearing a component part of the wholeadvertisement, and then successively rotating said bars by means of achain provided with a claw or claws adapted to engage projections on orconnected to the bars, means being provided to retain the bars inregister after rotation, such means, however, releasing the bars whenrequired either successively or simultaneously, as hereinafterdescribed.

Referring to the accompanying drawings, Figure l is an elevation of anapparatus embodying the invention and designed to give a gradual orprogressive exposure and change or obliteration, Figs. 2, 3, and 4;being de tails corresponding thereto. Fig. 5 is a fur ther detailrelating to Fig. 1. Fig. 6 is a view, partly in plan and partly insection, of a modified form. Fig. 7 is a detail relating to Fig. 6.Fig.8 is a transverse sectional View of the apparatus shown in Fig. 6.Fig. 9 is a view, partly in side elevation and partly in section, ofanother modification. Fig. 10 is a plan view, partly in section, of themodification shown in Fig. 9. Fig. 11 is a detail transverse sectionalview of the modified form of Fig. 9. Fig. 12 is a detail view of afurther modification.

In carrying out the invention according to one form, as illustrated inFigs. 1 to 5, the bars a, carrying component parts of an advertisementupon their peripheries, are arranged in vertical parallel series in aframework 1), provided with bearing-platesc for the axle pins d d at thetop and bottom of the bars. At one endof all the bars, preferably atthetop, projections h are provided, adapted to be engaged by one or moreclaws 2' upon a chain f, traveled byasprocket-wheel g, so that the barsare successively rotated. In order to keep the bars in register afterrotation, the chainblocksj are extended and adapted to engage the facesor ends of the projections 72, thus preventing any movement on the partof the bars until a claw engages a projection, a suitable gap i beingformed adjacent to each claw to allow rotation of the bar. If aquarter-rotation of each bar is desired at a time, four projections 71.are provided, as shown, thus furnishing four surfaces to be used fordifierent advertisements; but any other convenient number may be used.By this form of apparatus the exposure and change of advertisement areof a gradual or progressive nature. Guide-pins 22, supported on a bar23, attached to the framework, insure engagement of the claws with theprojections.

When it is desired that the advertisement after having beenprogressively exposed shall be instantaneously changed, the mode ofretaining the bars in register above described is inapplicable; but thebars may be still rotated successively by a similar claw-andchaindevice. Such an apparatus is. illustrated in Figs. 6 to S. In this casethe bars which are provided with projections h, as before, engagedsuccessively by one or more claws 7; upon a chain f, are retainedin.registor after rotation by means of pawls Z, engaging ratchets it onthe bars. The pawls are simultaneously released to allow a simultaneousreturn movement of all the bars under the action of returning-springs.The release of the pawls is caused by a projection t upon the chainengaginga lever to upon one end of a cross-shaft o, a lever 10 upon theother end of which at the same time engages a projection 00 upon a rod qand movesthe same against the action of a spring .9. The pawls which arepivoted on a bar not the framework are all formed with slottedextensions 0, engaged by pins 19 on the rod q, so that movement of thelatter, as above described, results in a simultaneous release of thepawls.

By suitably disposing the projection t upon the chain and by usingseveral claws, such as 11, a succession of advertisements may be exposedbefore the bars are released and instantaneously brought back to theinitial position. The bars are returned by the springs m.

The mode of holding the barsin register and simultaneously changing theadvertisement may be accomplished by causingthe bars to rotate stillfarther onward instead of back ward. Such an apparatus is illustrated inFigs. 9 to 12. In this case the projections 72. are not directly fixedto the bars, but to boxes 2, which are mounted loosely upon the axlepinsd at the top of each bar. The boxes are connected by spiral springs 2 tothe axle-pins, and besides the projections h are provided withadditional projections 3. The former, h, are engaged successively byclaws 't' i, the first of which winds up the springs and the secondimparts a partial rotation therethrough to the rollers. The projections3 are engaged by the chain-blocksj to prevent backward rotation or tohold the bars in register, suitable gaps 4 4 being provided adjacent tothe claws to allow rotation at the desired times. The forward rotationof the rollers is limited by stops 5, which engage with the pawls 6,carried by a shaft g, which is partially rotated in the bearings r, soas to simultaneously release all the stops 5, and therefore all therollers, when an instantaneous change of the completely-exposedadvertisement is desired. This release is effected in one convenientmanner bya projection 7 on the chain engaging a lever Sand impartingmotion, through a shaft 9, to a second lever 10, in contact- With an arm11 upon the shaft q, or, as shown in Fig. 12, a wormwheel 12, mounted onthe shaft 9, is rotated by a worm-shaft 15, which is provided with asprocket-pinion 16 directlyin gear with the driving-chain.

In order to prevent a backward rotation of the spring-boxes after thesprings have been wound, spring-pawls l7 and teeth 18 may be used inaddition to or instead of the arms 3. Aninitial tension maybeappliedtothesprings 2 before the spring-boxes are placed in position, so as torender the rotation of the roll ers more effective, in which case pins19 are provided on the rollers to engage within slots 20 in the boxes,so as to always retain the springs under tension.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An advertising apparatus consisting of a number of bars disposedadjacent to one another in the same plane so that the combinedperipheries present an advertising-surface, each bar bearing a componentpart of the complete advertisement, projections on the ends of saidbars, a chain, claws thereon for engaging said projections forsuccessively rotating said bars, and extended blocks on the chain forengaging said projections to retain the bars in register,as hcreinbeforedescribed.

2. An advertising apparatus consisting of a number of bars disposedadjacent to one another in the same plane so that the combinedperipheries present an advertising-surface, each bearing a componentpart of the advertisement, projections on the endsof the said bars, achain, claws thereon for engaging said projections for successivelyrotating said bars and extended blocks on the chain for engaging saidprojections to retain the bars in register, the said chain having gapsadjacent the claws to allow rotation of the bar, substantially asdescribed.

In witness whereof I have hereuntoset my hand in presence of twowitnesses.

CHARLES SCOTT-SNELL.
